Performs Cholesky factorization on a symmetric or Hermitian positive definite matrix.

## a

A symmetric or Hermitian positive definite matrix.

If a is not symmetric or Hermitian, this node uses only the upper triangular portion of a.

If a is not positive definite, this node returns an error.

Default: Empty array

## cholesky

The factored, upper triangular matrix. This matrix is $R$ such that $A={R}^{T}R$ for real inputs and $A={R}^{H}R$ for complex inputs.

## error

A value that represents any error or warning that occurs when this node executes.
